Choose the option which best expresses the given sentence in Indirect…

The correct answer is Option (2) → He said that he had given up his job.

Assertive sentence in indirect speech:

Change	Direct	Indirect	Why
Reporting verb	said, “	said that	“Said” has no object, so it stays “said”. “That” replaces the inverted commas.
Pronoun change	I, my	he, his	“I” becomes “he”, “my” becomes “his”.
Tense change	have given	had given	The reporting verb “said” is in the past, so the present perfect moves back to the past perfect: “have given” becomes “had given”.
Full sentence	He said, “I have given up my job”.	He said that he had given up his job.

Example: She said, “I have lost my key.” → She said that she had lost her key.

Why the Other Options are Incorrect?

Option 1: He said that he gave up his job. — Incorrect. The present perfect should become the past perfect ("had given"), not the simple past.

Option 3: He said that he gave the job up. — Incorrect. It uses the simple past and changes "my" to "the".

Option 4: He said that he had had given up my job. — Incorrect.

• "Had had given" repeats the helping verb, which is ungrammatical.
• "My" should change to "his".
